Jessica Chastain showed her support for Hollywood writers at the Writers Guild of America Awards in LA last night, while Lena Dunham snagged an award at the WGA's ceremony in NYC. The WGA Awards take place on both coasts — at the JW Marriott in LA and the B.B. King Blues Club in NYC — and each event was full of big winners.

Lena and her Girls writing team walked away with best new TV series, while Jessica's film Zero Dark Thirty won best original screenplay for Mark Boal. Meanwhile, Ben Affleck's Argo continued its award season sweep by picking up best adapted screenplay for writer Chris Terrio. Other big winners for the night included Fred Armisen, who won the best comedy/variety series award for Portlandia, and the writers of Breaking Bad and Louie, who won best drama series and best comedy series, respectively.

The award season fun isn't over for Jessica and the rest of the film industry as they prepare for the upcoming Oscars, which take place Sunday, Feb. 24.
